HAY-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 259,312, dated June 13,1882.

Application filed April 1. 1882. (No model.)

To all whom it may concern:

Beit known that we, JAMES li. HOWELL and JOHN lWI. HOWELL, citizens ot'the United States, residing at Academia, in the county of Juniata andState of Pennsylvania, have invented'certain new and useful Improvementsin Hay-Elevating Machines; and we do hereby declare the following to bea full, clear, and exact 'description ofthe invention, such as willenable others skilled in the art to make and use the same.

Our invention relaes to improvements in hay-elevators; and the object isto construct them so that they can be easily and quickly manipulated,are not liable to get out ot' order, and they can be readily applied tobarns, stables, or other places used for depositing hay, straw, &c.

The invention consists inthe construction and arrangement of parts of ahay-elevator, as will be more fully described hereinafter, referencebeing had to the accompanying drawings and the letters of referencemarked thereon.

Like letters refer to like parts in the different iigures of thedrawings, in which- Figure 1 is a side elevation of our improvedhay-elevator applied to a building. Fig. 2 is a plan view of the samewith the crane shown in the position for taking up a bundle of hay andin dotted lines for depositing the hay. Fig. 3 is a detail view of thelock-bar.

In the drawings, A represents a buildin g of any suitable size andconstruction for the reception of hay, straw, Sac. In this building isarranged a cross-beam, B, upon which is secured a base-block, C, and tothe rafters above a head-block, C', between which is pivoted a crane, D.The horizontal arm E of this crane is arranged in the rear ofperpendicular post D, andl is extended back ot' the main post, as shownat e, for the purpose of obtaining suicient leverage to revolve thecrane by the obliquity of the rope a from a sheave or grooved pulley, b,in an arm, c, secured to the beam B, to a sheave, d, in the extension e.Another sheave, d', is arranged in the outer end ofthe arm E.

A latch or trap, F, is pivoted or hinged to the arm E and supported in astirrup, f, on the outer end.

A bolt or double-headed pin, g, is placed in the outer end of the arm E,against which the latch F strikes when the fork with the hay comes incontact therewith as it is elevated, and thus releases a lock-bar, G.This lockY har is hinged or pivoted at one end to the rafters H of thebuilding, and has at its opposite end a head, i, and notch 7c, betweenwhich the arm E ofthe crane is held while loading the hay. On the innerside ot' the lock-bar G is secured in any suitable manner a slider, l,which forms the notch k with the head i.

A chain, q, supports the outer end of the lock-bar.

A brace, I, is pivoted to the lock-bar G and the head-block C', andserves to steady it.

Asheave, m, supported in a suitable bracket, is secured to the iioor,and a friction-roller, a, attached to the extension e, serves to keepthe rope a in a square manner on the sheave d.

A jack-rope, o, serves to bring the crane back to its normal positionafter the load ot' hay has been deposited in place.

A spiral spring, P, is preferably arranged on the rope a, over thehay-fork, to take up the shock in hoisting the hay.

The operation is as follows: The crane is held in the position shown infull linesin Fig. 2 until the hay-fork has been filled with hay, straw,Svc., when the operator draws upon the end of the rope c until thebundle of hay, Src., strikes against the pivoted latch F, which elevatesthe double-headed bolt g, and this releases the'lock-bar G from thecrane. The crane will then swing by its own weight, as well as theleverage obtained b v the Obliquity ofthe rope a, from pulley c to d tothe position shown in dotted lines, whereit is intended to deposit theload ot' hay, &c. A slight pull forward upon the jack-rope o returns thecrane again to its former position, where it will be again held by thelock-bar, by which it is automatically locked untilthe operation isrepeated.

It will be thus seen that the apparatus is automatic in its operationand is not liable to crane with a hinged lock-bar and a pivoted latch ortrap and suitable rope and pulleys, substantially as specified.

2. In a hay-elevator, the crane D, having th arm E arranged out of theperpendicular line of the crane-post, and provided with extension e forobtaining sufficient leverage to revolve the crane by the Obliquity ofthe rope a passing over pulleys c d, arranged substantially as setforth.

3. In combination Witha crane,D,thehinged lock-bar G, having head z' andnctch'c and slider Z, and supported by a chain, g, all substantially asand for the purpose specified.

4. In an apparatus for elevating hay, 85e.,

the combination of a crane, D, a hinged lockbar, Gr, and pivoted latch Fwith pulleys c d d and rope a, arranged substantially as shown, and forthe purpose set forth.

5. The combination of a crane, D, having arm E, pivoted latch F, anddouble-headed pin g, with the lock-bar G, brace I, pulleys c d d m,friction-roller n, and rope a, all arranged substantially as shown andspecified.
